What is soil compaction?
Compaction is the process of applying energy to loose soil or other material in order to increase its density and consequently its load-bearing capacity. This is accomplished by moving or rearranging particles closer together, eliminating trapped air and voids.
Why is soil compaction necessary?
Nearly all man-made structures are supported by some type of soil. Both residential and commercial construction can benefit from soil compaction in numerous ways. Benefits include the following:
Increases load bearing capacity
Prevents soil settlement
Decreases water seepage
Reduces swelling and contraction of soil
Prevents frost damage
What type of compaction equipment should I use?
The primary factor in determining the type of compaction equipment suitable for a given application is the type of soil involved. There are 3 types of soil used in construction application : granular, cohesive, and mixed soil.
